“The bass-baritone Kim Borg enjoyed a long and successful career as an opera singer, and was also greatly admired as a recitalist. His interpretations of German Lieder, notably by Brahms and Wolf, and of songs by his compatriots Yrjo Kilpinen and Sibelius, were deepened by sensitive musicianship and exceptional linguistic skills. Though his operatic career was mainly confined to Scandinavia and Germany, he sang for three seasons at the Metropolitan Opera in New York, appeared in Moscow, and was a welcome visitor at Glyndebourne.”

“Borg was engaged to sing the oily monk Rangoni to Christoff's Boris Godunov in Issay Dobrowen's ground-breaking recording of Mussorgsky's opera for EMI in 1952. Soon, Deutsche Grammophon was on his trail, and he made a number of recordings of opera, oratorio and song for the company during the following 10 years. Borg was much admired in Germany and, from 1965 to 1968, was a member of the Hamburg State Opera. But he was always welcome in his native Scandinavia, and from 1960 was a member of the Stockholm Opera, where his Scarpia was much praised in 1963. In 1971, he sang Fafner and Hagen in the company's performances of Wagner's RING. A year earlier, he sang Osmin at the Drottningholm festival, another histrionic triumph. He appeared in concerts at the Salzburg festival from 1956, singing Mozart, and in 1965-66 sang Pimen in Karajan's staging of BORIS GODUNOV.”
